The Steam page for Trackmania Turbo now offers a playable demo for the latest installment in Nadeo's racing series. Thanks to Frans for pointing out that in addition to a Steam account, playing this will require users to register with Uplay, Ubisoft's online service. It also looks like the demo can be acquired without Steam, as this page indicates it can be downloaded straight from Uplay (it also outs how late we are with this news, as it appears the demo came out in March). That page also includes details on the demo:
